<P><STRONG>Function</STRONG>
<P>
Add information from neighboring partitions to a Composite Field.
<P><STRONG>Syntax</STRONG>
<BR>
<TT><STRONG><BR>
&#35;include &lt;dx/dx.h&gt;<BR>
<P><BR>
Object DXGrow(Object object, int n, Pointer fill, ...)<BR>
Object DXGrowV(Object object, int n, Pointer fill, char **components)<BR>
</STRONG></TT><BR>
<P><STRONG>Functional Details</STRONG>
<P>
Recursively add boundary information to each partition of any
Composite Fields encountered in <TT><STRONG>object</STRONG></TT>.
<P>
The depth of overlap is defined by <TT><STRONG>n</STRONG></TT>.
The treatment of the boundary of the Field is specified by the
<TT><STRONG>fill</STRONG></TT> parameter:
specify <TT><STRONG>GROW_NONE</STRONG></TT> for no expansion at the exterior
boundary of the entire field;
<TT><STRONG> GROW_REPLICATE</STRONG></TT> to expand at the exterior boundary
by replicating the nearest edge values;
<TT><STRONG>GROW_NOFILL</STRONG></TT> to expand the exterior boundary by
leaving space for the extra data but leaving their value
undefined;
any other value of <TT><STRONG>fill</STRONG></TT> must be a pointer to a data
item of the correct type to expand at the boundary.
It is used as the fill value.
For <TT><STRONG>DXGrowV</STRONG></TT>, the <TT><STRONG>components </STRONG></TT>
Array contains a <TT><STRONG>NULL</STRONG></TT>-terminated list of
components to be grown; all others remain unaffected.
For <TT><STRONG>DXGrow</STRONG></TT>, the final arguments after
<TT><STRONG>n</STRONG></TT> consist of a
<TT><STRONG>NULL</STRONG></TT>-terminated list of
the components to be grown.  For each
component that is grown, the original component is renamed to
"original <I>component</I>" before the grown component is
created.
<P><STRONG>Return Value</STRONG>
<P>
Returns the input Object with the overlapping data added or returns
<TT><STRONG> NULL</STRONG></TT> and sets an error code.
If <TT><STRONG>o</STRONG></TT> is a field, returns <TT><STRONG>o</STRONG></TT>
unmodified.
